SASI-I-WEI GI-IT.

To all whom it may concern:

Be it known that I, JOHN B. LEE, a citizen of the United States,residing at Anniston, in the county of Calhoun and State of Alabama,have invented new and useful Improvements in Sash-\Veights, of which thefollowing is a specification.

The object of this invention is to provide a sectional sash weighthaving interlockin features of simple character but strong andsubstantial construction which are adapted to hold the sectionspermanently connected until one section is swung to a position at rightangles to the other.

Another object of the invention is to provide a sectional sash weightcapable of being easily cast and which will provide a much greaterweight for the space occupied than has been usual heretofore. Andfurther objects of the invention are to provide a sectional sash weightwhich will always hang plumb, which has a smooth rounded eye for thesash cord, and which is so constructed that it is not so liable to befractured in shipment or in use as other sash weights.

Referring to the drawings Figure 1 is a side elevation of two sectionsof my im proved sash weight. Fig. 2 is a front elevation. Fig. 3 is acentral sectional view showing one section located at a right angle tothe other. Fig. 41 is a fragmentary central sectional view showing thesections in alinement. Fig. 5 is a sectional view on the line 55 of Fig.2 showing the lower section in broken lines, except one trunnion whichis shown in full lines, the lower section being indicated at ,a rightangle to the upper section. Fig. 6 is a view similar to Fig. 5 showingthe sections in alinement.

For the purpose of this description I will refer to the section 7 as theupper and the section 8 as the lower section although it will beunderstood that these sections are always made identical in shape andvary only in size and weight. I may make the sections in a variety ofsizes and weights so that a sash weight of any desired weight may beeasily obtained. It will only be necessary, therefore, to describe onesection in detail.

Each section has at one end a tongue 9 which is provided with ellipticaltrunnions 10, their greatest diameter extending in the direction of thelength of the section. A hole 11 extends through the trunnions andSpecification of Letters Patent.

the tongue to receive the sash cord and the edges of this hole arepreferably rounded so as not to wear the cord. The tongue is tapered andthe front 9 thereof is flush at its base with the upper edge of thefront 7 of the section. This adds greater strength to the tongue andavoids a sharp shoulder extending entirely across the upper edge of thesection at the front thereof. The back 9 starts from the top of thesection at a point removed from the back 7 to leave a shoulder 12 forthe purpose hereafter described. The other end of the section isprovided with a slot 13 which is open at the front and end of thesection but is closed at the back thereof by a wall 11 which constitutesa part of the back 7 of the section. The top wall 15 of the slot isinclined upwardly from the back wall 14:, or adjacent thereto, to thefront of the section. The inner faces of the side walls of the slot areeach provided with a recess 16 which has a straight top wall 17 andprovides a throat for the trunnions. The bottom wall of each recess 16is straight at 18 extending from the open end of the slot inward to thepart 19 which is curved to form a bearing for the trunnion 10.

Two sections of my improved sash Weight are assembed by arranging themat right angles to each other and then inserting the tongue of one inthe slot of the other, as shown in Fig. 3, after which the sections areswung to alinement. The two sections will be locked together in anyposition except when at right angles. The recesses 16 are just wideenough at the front between the part 18 and the top wall 17 to form athroat which will permit the trunnions to slide freely therethrough whenthe sections are arranged as shown in Fig. 3, and the curved part 19 ismade complementary to the lower part of the trunnion so that the latterwill work freely in its bearing. The slot has the inclined top 15 toprovide space for the inclined front wall 9 of the tongue, as shown inFig. 3, and the tongue is constructed in this manner to provide as muchmetal as possible to strengthen it. The back wall 14: of the slot isarranged to engage the shoulder 12 and the parts are constructed so thatthe two sect-ions will hang flush wit-h each other at their front andback and side walls.

In practice I prefer to assemble the sections in the manner indicated inthe drawings in which the tongue is uppermost. This permits the lowersection 8 to be engaged with the upper section 7 by arranging it in ahorizontal position and inserting the tongue in the slot, then allowingthe lower section to swing down to an upright position. It is convenientto attach the upper section 7 to the sash cord and then add additionalsections as required to supply the required weight. This can be easilydone by assembling the sections in the manner referred to and asindicated in Fig. 3, the construction permitting additional sections tobe connected to the top section by inserting them through the opening inthe window frame after the top section has been connected to the sashcord.

What I claim and desire to secure by Letters Patent is:

1. A sectional sash weight, each section consisting of a body portionprovided at one end with a slot open at the front and end and closed atthe back, the side walls bein recessed to form a throat and bearings,and the forward top side of the slot being inclined upwardly to providefor the reception of a tongue portion of an interlocking section, and atongue portion at the opposite end provided with hollow trunnions forinterlocking with a contiguous section, or for the attachment of asupporting cord thereto.

2. A sectional sash weight, one section having a tongue projectingoutward from its end, elliptical trunnions on said tongue having theirgreatest diameter extending in the direction of the length of thesection, there being an opening through said trunnions and tongue toreceive the sash cord, said tongue being tapered and having its frontflush at its base with the upper edge of the front of the section andits back offset at its base from the top of the back of the section, theother section having a slot shaped to provide a throat to permit thepassage of said tongue and bearings in the side walls of said slot forsaid trunnions.
